Patent number: 8718463Abstract: An adapter for controlling a first camera and a second camera, which exhibit differing operating characteristics, in a three-dimension (3D) camera imaging system. The adapter provides a camera control signal to the first camera to control operation of the first camera. The adapter converts the camera control signal to a second camera control signal utilizing information from the first and the second cameras indicative of imaging states of the cameras, and provides the second camera control signal to the second camera to control operation of the second camera. The conversion compensates for the differing operating characteristics of the first and second cameras.Type: GrantFiled: December 9, 2010Date of Patent: May 6, 2014Assignee: Sony CorporationInventors: Koji Kamiya, Seiji Sato, Tomoyasu Katsuyama
